The described embodiments are implementations that are part of this application and not all implementations. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application, and should not be construed as limiting the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application. Embodiments of the present application will be described in detail below with reference to the drawings.

The invention aims to solve the problems that an electric interface and an air circuit interface are difficult to butt joint and separate when a missile in an embedded missile cabin of an airplane is hung or disassembled, the butt joint and the separation are difficult to realize, and the maintenance time is long. Shown as connector plug 1; the connector socket 2 is arranged on the top of a buried bomb bay in the airplane, and the automatic butt joint and separation of an electric interface and an air circuit can be completed when the missile/hanger assembly is lifted/lowered.

The plug is by plug housing assembly (including plug housing, clamp plate, fastener), afterbody annex (including afterbody safety cover, outlet clamp plate, fastener), insulator subassembly (including preceding insulator, back insulator, jack catch, the sealing line body, crimping jack), can increase the gas circuit export according to the demand.

The function of the shell component is as follows: the connector is provided with supporting and protecting functions; the connector is inserted in place to play a role in limiting.

An insulator assembly: the fixed positioning claw is bonded to the front insulator and the rear insulator, so that the contact body is fixed in the connector, the tail portion is bonded with the wire sealing body, the tail portion of the connector is sealed, and sand and dust and other impurities are prevented from entering the connector.

The socket comprises a socket shell component (comprising a socket shell, a pressing plate and a fastening piece), a tail accessory (comprising a tail protective cover, a wire outlet pressing plate and a fastening piece), an insulator component (comprising a front insulator, a rear insulator, a clamping jaw, a wire sealing body, an interface sealing body and a crimping contact pin), and a gas path outlet can be increased according to the requirement.

Because the series of connectors are used for realizing signal and air path transmission between the airplane body and the missile hanging frame, when the machining precision of the airplane body and the missile hanging frame is insufficient or the installation size has errors, the butt joint is difficult to realize, and the butt joint can not be realized seriously. In order to avoid the problems, the invention designs a floating installation mode, the floating sleeve is fixed after installation, and the connector can perform plane movement within a certain range, so that the installation mode can effectively avoid the butt joint difficulty caused by the problems of machining errors, installation errors and the like.

Because the hanger hoisting mechanism has installation and manufacturing errors, in order to ensure the effective butt joint of the connector, the connector has a butt joint guide function, a guide pin and guide cylinder structure is designed for the connector, a pair of guide pins and guide cylinders are respectively installed at two ends of the connector, and the guide pins and the guide cylinders of the connector are designed into regular sizes with different sizes while considering the butt joint guide function, so that the connector has the capability of preventing misplugging.

Because the connector is in blind-mate butt joint, in order to accurately judge whether the connector is in place in butt joint, the connector is designed with a butt joint in-place recognition function. A pair of signal points is added on the connector to form a loop, when the connector is in a butt joint state, a signal is conducted, and when the connector is in a butt joint state, a signal is broken, the butt joint state is not in a butt joint state, and the specific steps are as follows:

when the connectors are butted, because space is willing, whether the butting is in place cannot be judged, two hole positions are reserved in the connectors, contact bodies with different lengths are respectively installed, and the length of a long pin and a short pin is controlled to help judge whether the butting is in place. The operation time is judged according to the following method: when the long pin and the short pin are both connected, the connector is in butt joint in place, and when the long pin and the short pin are both disconnected, the connector is separated.

When the hanging rack is connected with the machine body, the phenomenon of angle deflection may exist. To calibrate out-of-tune deflection angles, we add self-aligning structures to the design that allow deflection angles of up to ± 3 °. The plug, the guide effect of guide pin 3 and position sleeve 4 of socket, the plane floating capacity of floating screw and the axial floating capacity combined action of spring, the connector can calibrate the deflection angle of maladjustment in the butt joint process, guide pin 3 at first gets into position sleeve 4 when plug, socket dock, and continue to insert by the guide of guide pin 3, there is certain clearance between 3 external diameters of guide pin and the 4 internal diameters of position sleeve, and the guide pin head is the toper structure, position sleeve 4 can float between socket flange hole, when plug, when the seat butt joint face takes place to deflect, realize the butt joint function through the toper structure of guide pin and the clearance between the guide cylinder.

The invention also has a gas path structure, thus designing the installation space of the gas path. In order to facilitate the manufacture of cables and gas circuits and the later maintenance, the cables and the gas circuits are designed into mutually independent structures so as not to influence each other. The air circuit module is directly communicated to the outer side of the mounting disc through the auxiliary conduit assembly, and when the air circuit module is used, a user can firstly access a cable and bunch the cable, and then accesses the vent pipe into the connector through the conduit assembly.

The influence of the mode of being qualified for the next round of competitions is synthesized, is the multiple structures such as the side is qualified for the next round of competitions, is directly qualified for the next round of competitions with the design of afterbody annex according to actual demand, and tail annex design shielding structure simultaneously, accessible steel ribbon realizes the circumference shielding to preventing that the ripples cover is fixed, but the clamp plate centre gripping cable, convenient preparation.

Compared with the existing aviation connector, the connector has obvious advantages in the aspects of integration, installation mode, use and maintenance and the like, can obviously improve the efficiency of hanging, replacing and loading the missile in the embedded missile compartment, and reduces the supply time. The method is mainly characterized in that:

1) The plug has single-cavity and multi-cavity models, and meets various electrical requirements between different airplanes and hangers;

2) The prior missile system aviation connector mostly adopts a circular connector, only an electric contact is provided in the connector, and no air passage interface is provided;

3) When the existing circular connector is inserted, manual visual observation and screwing are needed, and whether threads, bayonets and the like are butted in place or not is checked visually. The invention can complete the automatic butt joint and separation of the electric interface and the air path in the ascending and descending processes of the launcher/hanging rack assembly without manual operation;

4) The existing circular connector adopts a fixed installation mode, and when machining errors or installation errors exist, butt joint is difficult. The invention designs a floating installation mode, the floating sleeve is fixed after installation, and the connector can perform plane movement within a certain range, so that the problem of difficult butt joint caused by machining errors and installation errors is solved;

5) Whether the existing connector is inserted in place can only be judged by experience or checked by eyes. The invention designs the in-place docking signal which is directly sent to the airplane, and the airplane can quickly judge whether the in-place docking is performed according to the state of the signal, so that the accuracy is improved, the efficiency is improved and the task reliability is improved compared with the manual judgment.
